HARDWARE PAGE WRITE PROTECT:
If the WP pin is
held low, the first 256 pages of the main memory cannot be
reprogrammed. The only way to reprogram the first 256
pages is to first drive the protect pin high and then use the
program commands previously mentioned.
RESET:
A low state on the reset pin (RESET) will terminate
the operation in progress and reset the internal state
machine to an idle state. The device will remain in the reset
condition as long as a low level is present on the RESET
pin. Normal operation can resume once the RESET pin is
brought back to a high level.
The device also incorporates an internal power-on reset cir-
cuit; therefore, there are no restrictions on the RESET pin
during power-on sequences.
READY/BUSY:
This open drain output pin will be driven
low when the device is busy in an internally self-timed oper-
ation. This pin, which is normally in a high state (through an
external pull-up resistor), will be pulled low during program-
ming operations, compare operations, and during page-to-
buffer transfers.
The busy status indicates that the Flash memory array and
one of the buffers cannot be accessed; read and write
operations to the other buffer can still be performed.

*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
